1.67 mol S

General Formulas and Concepts:

Chemistry - Atomic Structure

• Reading a Periodic Table
• Using Dimensional Analysis

Step-by-step explanation:

Step 1: Define

53.7 g S

Step 2: Define Conversions

Molar Mass of S - 32.07 g/mol

Step 3: Convert

`53.7 \ g \ S((1 \ mol \ S)/(32.07 \ g \ S) )` = 1.67466 mol S

Step 4: Check

We are given 3 sig figs. Follow sig fig rules and round.

1.67466 mol S ≈ 1.67 mol S
